REVERSIBLE TREAD MEMBER FOR WITEELS.

and has special reference to the tread members or spuds of tractors andlarge motor driven farm vehicles or implements. State, county and cityauthorities prohibit the operation of a tractor having permanent treadmembers or spuds traveling on paved streets or good roads, as the treadmembers or spuds out into the street or road and eventually ruin thesame. In order that a farm tractor or implement can be moved on streetsor roads, without injury to the same, aid yet have the proper tractivepower in a field, I have devised a novel reversible or invertible treadmember or spud that may be easily and quickly extended or retracted,relative to the rim of a wheel, either to present protuberances on theperiphery of the wheel or a smooth tread or rim.

My invention further aims to provide simple, durable and inexpensivemeans for at-' tachin a tread member or spud to the rim of a wheel, sothat the member or spud may be positioned on either side of the wheelrim.

My invention still further aims to provide tread members which willpermit of clogged earth and other matter-being quickly and easilyremoved from the rim of a wheel, and the construction of my inventionwill be hereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein Figure '1 isa plan ofthe inner wall of a wheel rim provided with a tread member in accordancewith my invention;

tlon of a wheel rim provided with a tread member, illustrating a slightmodification of my 1I1 VBI1tlQl'1; LI1d Fig. 7 1s a cross sectional viewof the same.

In the drawing, the reference numeral 1 denotes a portion of a wheel rimprovided with sets of transversely alining slots 2 and these slots maybe equally spaced about the llIn or periphery of the wheel. The rim 1may also have inwardly extending annular side flanges 3 or may have anyother desired cross-sectional shape.

Connected to the rim 1, by rivets 4 or other fastening means, and ateach set of transversely alining slots 2, are the lateral flanges 5 ofparallel guides 6, each guide being preferably in the form of an anglebar. The guides 6 have the confronting walls thereof flush with thelongitudinal walls of the slots 2 and said guides also serve as braceson the inner wall of the wheel rim. I

7 denotes a tread member having a set of lugs 8 spaced according to theslots 2 and her 7 has angularly disposed ends 9, as best shown in Figs.4 and 5 and when the tread member is on the outer wall of the wheel rim,the angularly disposed ends 9 extend to the side edges of the rim andcooperate with the tread member in providing a good tractive element.When the tread member 7 is inverted and placed at the inner wall of thewheel rim, as shown in Fig. 2, the angularly disposed ends 9 of thetread member rest on the guides 6 and position the lugs 8 between saidguides so that, the ends of the lug close the slots 2 and provideajsmooth periphery for the wheel rim 1.

The lugs '8 of thetread member areiprovided with openings 10 adapted toregister with openings 11 in the guides 6, and in addition to theopenings 11 there are intermediate openings 12.

13 denotes a locl ingmember having end prongs 14 and an intermediateprong 15 with the end prongs 14 extending through the openings 10 and11, the intermediate prong 15 extending through the openings 12, betweenthe lugs 8 of the tread member.

The intermediate prong 15 is of greater.

; permit of guides 6, intermediate the ends thereof, said look oaslnghevlng an opemng provldlno; clearance for the n'xtern'xedmte prong. The

outer end of the intermediate prong 15 has a cross p1 eide{32"168'510118 1? that preewzd of the look be ides 6, said inter mediatepi'ol Y of sufficient length to be looking member being retracted toname the end prongs let out of the openings 10 of the tread. member lugs8, thus permitting of the tread member being Withdrawn from between theguides 6.

one of the guides 24 is a post 26 for a spring 2"? adapted to have itsends engage the end prongs of the locking member 25, as best shown inFig. 7. By first releasing one end of the spring 27 the opposite endthereof will be automatically moved and thus restructural elements aresusceptible to such Variations and modifications as fell within thescope of appended claims.
